00:00Iranian engineers have tested a large solid-fuel rocket motor connected to the KM satellite
00:04launcher program. The motor was bolted to a ground stand for the burn, a static fire,
00:09used to collect performance data on the nozzle, the burn profile, and overall propulsion behavior
00:13before anything flies. The size is the story. At roughly 2.4 meters across, it's considerably
00:19larger than the Salman and Rafay boosters on earlier KM vehicles. That's not an incremental
00:24upgrade. Iran is building toward a heavier launcher. A motor this size opens the door
00:28to heavier satellites. It also develops the same propulsion technology that applies to
00:32long-range ballistic missiles, something Tehran hasn't commented on and probably won't.
